My custom license plate doesn't works

I made myself an brazillian driving school license plate mod using the wiki tutorial page and template. I made everything correct, but when I put the license plate on the car, it appears "no texture"
Also, I deleted the original from template and replaced with mine (it's PNG), and renamed the json and jbeam file, was it because that?
(yes, I didn't know about mod support option and posted here unintentionally)

 

Are you sure you absolutely did everything correct with the license plate image and its associated file path?

 

Try it on a default vehicle. Maybe not a mod

 

Can you upload the files? Or at least show us?

 

try to work with default plates

 

I tried on an D-Series, but still doens't works

I think yes, I'll try again later

I'll try it

Here is it:
(sorry if the license plate have bad quality, i picked the original from Google and removed lettering just for testing)
Also tried to change the font

 

Aren't those backslashes supposed to be forward slashes? I've never seen backslashes inside a file like that. Or maybe I'm 100% wrong. (probably)

 

No, the slashes are supposed to be /. If they were \, it won't register it.

 

I corrected the slashes, still haves no texture

 

Hmmm, I have no idea what can be causing this, then.
